Grease a 9x13-inch pan with butter or oil. Place the cubed bread inside, filling three-fourths of the dish, and spread them out evenly.
02 -
Whisk the eggs, milk, vanilla, cinnamon, and sugar in a big bowl until smooth and fully blended.
03 -
Evenly pour the egg mixture over the bread cubes in the pan. Scatter blueberries, strawberries, or any berries you like on top.
04 -
Seal the pan with plastic wrap and chill it in the fridge for 4 hours or overnight to let the bread absorb the mixture.
05 -
Set your oven to 350°F (175°C). Take the casserole out of the fridge and bake for 35-50 minutes. Start checking at 35 minutes; it should have crispy edges and a firm middle that's not dry.

Dust the finished dish with powdered sugar if you want, then drizzle it with maple syrup before digging in. Bacon or other breakfast favorites go great on the side.
